Technisonic Dual Audio Controller The Technisonic TAC-200A Dual Audio Management System was designed to provide superior performance for those installations requiring two completely independent audio controllers in a single panel mounted configuration. Separate pilot and co-pilot transmit selector switches enable two operators to select any of the aircraft communications transceivers or PA amplifier, while input audio selector switches for each input allow selection of any or all of the available aircraft audio inputs. Additionally, any of the 8 inputs can be switched (internally) to operate on either side of the controller. The TAC-200A features front panel adjustable and selectable, VOX, LIVE or KEYED intercom (ICS) for both pilot and co-pilot positions.. The function of the ICS pot is to control the vox trigger level. When the ICS pot is rotated to the fully ccw (OFF) position, intercom operation is push to talk. When turned fully cw, live ICS operation is enabled. A locking EMERGENCY/ ISOLATE/NORMAL mode switch is provided, which enables "straight through" transmit and receive audio for the pilot, on the selected radio in the EM (Emergency) position and pilot isolation from the intercom bus in the ISOL position. In the NORMAL position the pilot is included on the shared intercom bus which can include up to 6 positions. Input provisions include two VHF/AM COM positions, two FM transceiver positions, an AUX position (which can operate as a third FM), and a PA position which will drive any of the commercially available PA/Siren systems. This high power audio controller delivers 500 milliwatts of audio (per side) into 600 ohms at less than 5% distortion. Due to Technisonic's multi-layer board construction, hum and noise as well as inter channel cross talk are kept to a sub-audible level. The TAC-200A pin-out is compatible with the new optimized ACCESS/A Interconnect Standard. The small size, and light weight of this superior audio management system make it ideal for helicopter installations. The TAC-200A meets all requirements for "contractor furnished avionics" as outlined in the latest US Forest Service Contract requirements. Compare These Features The TAC-200A Dzus panel mounted audio management system is completely self contained and fits into a 5.75 (W) x 1.87. (H) x 6.35 (D) slot. The entire controller (including connectors) weighs just 2.5 pounds. Front panel controls are separate, concentric ICS and Receive volume for both left and right, Transmit selector for both left and right, an ISOLATE/EMERGENCY/NORMAL mode switch, an ICS vox threshold control, and eight pilot selectable receive input switches. The TAC-200A can support up to six headsets. Technisonic audio controllers can be ordered with either 28 VDC (standard) or 5 VAC (Specify) backlighting, which is controlled by the aircraft dimmer bus. Technisonic audio management systems are compliant with TSO C50c and RTCa DO-160C categories relating to Vibration, Humidity, Temperature and Altitude, ensuring top performance at an affordable price.
